Operators on Lorentz sequence spaces [PDF]

Mathematica Bohemica, 2009
Summary: A description of multiplication operators generated by a sequence and composition operators induced by a partition on Lorentz sequence spaces \(l(p,q ...

Homogeneously Modified Special relativity (HMSR)

European Physical Journal C: Particles and Fields, 2019
This work explores a Standard Model extension possibility, that violates Lorentz invariance, preserving the space-time isotropy and homogeneity. In this sense HMSR represents an attempt to introduce an isotropic Lorentz Invariance Violation in the ...

Discrete Lorentz symmetry and discrete time translational symmetry

New Journal of Physics, 2018
The Lorentz symmetry and the space and time translational symmetry are fundamental symmetries of nature. Crystals are the manifestation of the continuous space translational symmetry being spontaneously broken into a discrete one.

Estimations of the best M-term approximations of functions in the Lorentz space with constructive methods

Қарағанды университетінің хабаршысы. Математика сериясы, 2017
This paper considers the Lorentz space of periodic functions of many variables with the anisotropic norm, of functional Nikol’skii-Besov’s class and of the best M -term approximation of function.

Improved Epstein-Glaser Renormalization II. Lorentz invariant framework [PDF]

, 2002
The Epstein--Glaser type T-subtraction introduced by one of the authors in a previous paper is extended to the Lorentz invariant framework. The advantage of using our subtraction instead of Epstein and Glaser's standard W-subtraction method is especially

Formulation of the Lorentz transformation equations in the three dimensions of space

St. Petersburg Polytechnical University Journal: Physics and Mathematics
The Lorentz transformation of space and time between two inertial frames of reference is one of the pillars of the special theory of relativity. Until now, the Lorentz transformation equations have been considered on the base of one-dimensional motion ...

Is Torsion a Fundamental Physical Field?

, 2007
The local Lorentz group is introduced in flat space-time, where the resulting Dirac and Yang-Mills equations are found, and then generalized to curved space-time: if matter is neglected, the Lorentz connection is identified with the contortion field ...

Covariant Space-Time Line Elements in the Friedmann–Lemaitre–Robertson–Walker Geometry

Axioms, 2022
Most quantum gravity theories quantize space-time on the order of Planck length (ℓp ). Some of these theories, such as loop quantum gravity (LQG), predict that this discreetness could be manifested through Lorentz invariance violations (LIV) over ...
